Not sure what it is nor do I know whether it's the same thing, but when my vision began to deteriorate I started seeing fuzzy shadows with random shapes in the periphery of my vision field that disappeared when I blinked, and as my glaucoma progressed, started appearing in places increasingly closer to the center. In very early stages I just thought it was my hair since I had long hair at the time, but not long after I started suspecting it was the beginning of a retinal detachment so had it checked and it turned out to be nothing. I also remember that, after a glaucoma surgery to implant a shunt, my intra-ocular pressure became very low and the shadows concentrated at the top of my field of view, which made me believe I had blood inside the eye until my eyeball healed, the pressure went back up, and the shadows started appearing at random locations again. Nowadays, after losing all my residual vision, the shadows still appear and sometimes cover what used to be my entire vision field which is otherwise filled with hallucinations of what my brain thinks is around me. So in conclusion, and at least in my case, I strongly believe that it's neurological.

I have all sorts of blobs and swirls that move in my vision. Doc guesses they are floaters. Some are completely opaque and others are kinda see through. My entire remaining visual field looks like an old movie with static and white lines and flickering black and white spots all over it and they’ve decided that is neurological.

Hmm,

For me, sometimes I see randum orange shaped black shapes moving through my field of view, they disappear if I focus with my eyes hard. My Eye condition is Star guardts disease with mild nystagmous.
